Terrariums and Mini-Gardens! Because Everybody’s Doing it

A friend of mine was telling me about a terrarium he recently made. I wasn't quite sure what it was until he showed me. He not only had a shelf dedicated to his terrarium, but he was in the process of building a miniature garden as well. What a fun idea that anyone can get involved in!

This idea is especially great if you don't have yard space to have something like a garden or anything. Since I'm in a rented duplex, I haven't bothered with gardens or anything like that, but these you can keep inside, even, on a shelf with a grow-light.

It something I'm going to look into doing for myself. Have you made anything like this? Any tips, put them in the comments.
